If your coating specification requests bright pink, orange, green, or yellow, you are able to cut down the project time. You can also cut down on the amount of paint used when the specification calls for a bright color.
Instead of using a typical dark or gray prime coat, use a bright white top coat to achieve the bright top coat faster.
Choosing an intermediary color, specifically a bright white primer, will make your life easier. With the bright white, you will most likely be able to finish way quicker than using a dark primer, because you will only have to put one top coat on instead of multiple.
This tactic will save you money, time and paint!
